In the form of my invention shown in Fig. 5, instead of moving the cutter 191 it is mounted on. u fixed frmne 391 and the boiilo 2G is nmcie vertically movable, moi'enieiii, being imported to ii by the rod 39% connect-- ecl with ihe bellows device 34 21nd thereby the bottle closure forced over the cutwiand cut open. In Fig. no suitor has a iluemieil siiznnk 481, by which it is adjustublji attached, to the supporting frmtoe 393. iinii in may be moved 51o position not to interfere with the i'emovui oi the bottle or its replacing in tile fmme 391, which sup-- ports iii. As clearly shown in 6.. the cutter 40 is maria separate from the si anlq Q81 anoi upon its tapering; extevior iizei'e clownwiiidiy projecting .nai'b-lii-ie ribs 2:05 and the numbing edge is interrupted for about one-third of the cii'eumfel'once by u uotoli or depression 06. With this consiiuotion when the cutter 40 is forced. through illlfi bottle closure only a portion of the letter will "be severed. no out being made opposite the notch 4:06, but the SGVQIEKi portion, Wiil. by the upward movement of the nutter be forced up into the bottle. renmining iii-inched by the uncut poi'fiion and the burns 405 will interlock with the edges of the out and the cutter 4-0 will thereby be retained in ifhe bottle when. the shank 40]. is ufteif'vvmd Wit-iidmwn. Thus, I maize it-eertaiu blni; there will, no UiJSiIIIZCfiOn to the eiiiux of the .contnts oi the bottle and provide through the cutter 4-0 a clear passage for no liquid oonients of time bowie. If desired, in midi-- biofi to the central hole 402. the cutter um be provided With' the inclined holes 403 which Will enable (lie sulfuric acid to pass into 'iihfl opening 402 from the side. It \Vili be seen that by reason of the notch 40K? the f suitor does not (oiiipletely sepumte the disk which it cuts out of she stopper, but leaves ii: attached for a short clistzmee, and beii'ig so attached. and as a result of the continued thrusting movement of the cutter tile p;i.1--..

iially out out disk will be bent upon is wonncction with the bottle and thrust upward and to one side oi? the cutter so that it wiii 1 finally be squeezed between ilie'sifle of i'lio cutter and inside of the bottio neck. thus lemony: an absolutely unobstructed passage blirongh the hole 402 11" may be desirable in some iusiullutions, especially on slnphozuci, to have snmll uppu-i'utuses, us far as the exiiuguishiug fluid and ressurc tanks are concerned.. e sup ily of chemical (*li llllglllallfil. Winn-1 ordinarily would. be 1 adequate. lecesion might arise, however, lot a, larger supply of chemical extinguishing fluid, To n ieet this requirement I have deviserl the embodiment of my irwention illustrated in 8, i lch shows a number of separate units A three) said units being shown comprising the chemi cal extinguisher and pressute ilfi-lll fS and supply pipes having the sprinkler head. equip-- ment, each unit being independent of one other; and a unit B that comprises ohemicol extinguisher holding tank 10 oi it go capacity and e pressure tank 19 of lame capacity, From the chemical extinguisher tank 10 a. pipe 11 leads, which lies 2, number of branches 110 corresponding with the number of units A, one branch 110 being connected with the supply pipe oi one of the unite, Each branch 110 lies at 'GlIGClSZ valve 11 which prevents back pressure loom,

the supply pipes of one of the uni be cause in such unit end supp y n e e UFO- V v sure normally superior to that in the tenlt 10 of the unit B is nieinteinecl, enil it is only after the practical exhenstion of the chemical extinguisher from o unit A that thesupplementel ox' auxiliary supply from the unit B is cellecl into requisition. A, check valves; is provided in the supply pipe of each unit A that prevents back pressure into the chemicalextinguisher tank of the unit A, but when the pressure in. the ohezxi eel extinguisher tank in the u" n B ale that of the residual pressure in the chem c extinguishinn; tenlz of the unit- A, then the (il'iemicul extinguishers from. both tenliswill flow to the supply pipe.

It will be seen. that ley the arrangement illustrated in 8, the auxiliary supply of chemical extin misher is available to any one of the sei 'iee of units A which may he called into operation when the fire (selling it into operation requires a greater supp of chemical extinguisher than the unit itself can provide.

It will be umlerstoodthat the generation of pressure-producing gas by the mixing oi sulfuric acid and soda solution in the unit B is efl'eetuated automatically in oonsequence of the reduction of pressure in the chemical extinguisher tank 10 due to the cfilnx of such exting-u ion-occasioned by the demands mecle upon it by one of the units All,

It will be seen that en though the ope1tetion of any one unit A may result in ing all of ins supply of extinguish mil all of the supply the 41ml;

that the remaining n est for action ,eion of pie;
